WOW, great idea. We came from a 17' Casita where we limited the hanging portion of the closet to 8" and converted the rest to shelving. It came out great and sure made our camping experience nicer. My design was complex and added a bit of weight, so seeing your's has me thinking. I plan on converting our new 21 closet to about 9" of hanging and 12" of shelving, hum! Thanks for sharing,
